Dear Mr./ Ms.Strange
Genome sequencing may be an appliable by splicing the genes with sunject zero with realitivly reconisable gene patterns with another animal say parent 1. You maybe able to quantify the development of an artifical embryo. An allow some respective genes to be left out through the first generation. This will allow the gustation of the original embryo from Subject zero and Parent 1.
Then slowly adding in the missing genes through generations 2 and 3. By this time you may have been able to map the genome of daughter 3 and compare it to Subject zero's base broken genome. This will allo you to fill in the gaps through mutation and other reconizable physical genes that you see fit.
For the final generation you create that you feel is about 89% correct in shape and stance. Use the remants from Subject zero's genes to synthize and artifial zygote to mix with the final generations this will allow you to filter out the flaws and create a 99% accraute lifeform which we will call "Proto 1" for now, Please enjoy.
I redact the greeting on my original post i meant to say Dear Mr./Ms. Fish
